Time and distance are for a return trip. The trail to Lake Janet in Glacier National Park is most easily accessed from Goat Haunt at the south end of Waterton Lake. This would necessitate a trip into Canada and a boat ride from Waterton townsite. You could, of course, come in from Logan Pass, and avoid the trip to Canada but would add 50km (30 mi.) to your trip (okay if you're backpacking anyway).
Lake Janet is in a remote part of the north end of the park. It's part of the Brown Pass trail system. The trail is mostly easy with a couple of short, steeper sections. From Goat Haunt (Ranger and Customs station) the trail first crosses the Waterton River on a suspension bridge then turns west to follow Olson Creek. Views at the lake are amazing, the campground is a little ways past the lake. rumour has it that the views a Lake Francis (about 5km further) are even more amazing.
SPECIAL NOTE - Goat Haunt is a Class B border crossing into the U.S. from Canada. Only Canadian and U.S. citizens (with passports) are allowed to hike past Goat Haunt UNLESS prior arrangements have been made at a regular customs office.
Goat Haunt can be reached via boat, either private or commercial from Waterton Lakes National Park (Canada) or by the Waterton Lakeshore Trail, also from Waterton.
